The hollow part 111 may be formed surrounded by a sidewall of the body 110 . For example, the hollow part 111 may be formed in a size (a vertical passage shape and size) that an operator can move in an up-down direction (referring to FIG. 1, 12 o'clock-6 o'clock), and also, the body ( 110), an inspection ladder may be installed inside the side wall to enable movement in the vertical direction of the operator.

In addition, the hollow part 111 is a space formed for the inflow of rainwater into the body 110 . Accordingly, in the body 110 , an inlet hole 112 may be formed in the side wall so that the rainwater inlet pipe 121 for inflow of rainwater from the outside to the hollow part 111 can be installed. The rainwater inlet pipe 121 installed in the inlet hole 112 may have an outer end thereof connected to another external pipe or may be connected to an external water collecting structure.

In addition, an outlet hole 113 may be formed in the body 110 to allow the installation of a rainwater outlet pipe 113a for discharging the introduced rainwater to the outside of the hollow part 111 .

For example, referring to FIG. 1 , the outlet hole 113 of the body 110 may be formed at the same height as the inlet hole 112 or at a lower height than the inlet hole 112 . That is, the inlet hole 112 may be provided to be positioned at the same or higher position than the outlet hole 113 , rather than being positioned at a lower height than the outlet hole 113 in order to maintain a head difference for preventing backflow.

Referring to FIG. 1 by way of example, the inlet hole 112 and the outlet hole 113 may be respectively formed on sidewalls of the body 110 that face each other, but the present invention is not limited thereto. It can be set in various ways in consideration of site conditions, design, scale, etc. As another example, the inlet hole 112 and the outlet hole 113 may be respectively formed on sidewalls connected to each other adjacent to each other.

In addition, the sediment separation unit 120 can be said to be a spatial configuration that forms a space for the sediment separation in the lower portion of the hollow portion (111). Referring to FIG. 1 , the sedimentation separator 120 induces sedimentation (separation from the inflowing rainwater) of a solid material with a large specific gravity such as sand and gravel having a large particle size among the rainwater introduced through the rainwater inlet pipe 112a. can do.

Referring to FIG. 1 , the screen tank 100 may include a solid-liquid separation screen device 130 . The solid-liquid separation screen device 130 may be disposed at a height between the sediment separation unit 120 and the inlet hole 112 . The solid-liquid separation screen device 130 has a predetermined height or higher (height considering the sedimentation separation space of the lower part of the hollow part) so that foreign substances having a relatively large specific gravity among the introduced rainwater are separated by sedimentation and accumulated in the sedimentation separation unit 120 . It is preferable to be installed to be located in In addition, the solid-liquid separation screen device 130 may be located below the formation height of the inlet hole 112 to separate (filter) the solid and liquid from the introduced rainwater. Accordingly, foreign substances with a large specific gravity among the rainwater introduced through the inlet hole 112 are firstly induced to settle in the sedimentation separation unit 120 , and at least some of the foreign substances that have not been precipitated go through the solid-liquid separation screen device 130 . It may be discharged through the outlet hole 113 while being separated.

2 to 4 are diagrams for explaining the solid-liquid separation screen device of the underwater sedimentation screen tank according to an embodiment of the present application. More specifically, FIG. 2 is a partially enlarged conceptual view of a part of FIG. 1 for explanation of the solid-liquid separation screen device of the underwater sedimentation screen tank according to an embodiment of the present application, and FIG. It is a conceptual diagram looking at the silt screen tank, and FIG. 4 is a conceptual diagram for explaining the filtration unit.

In addition, referring to FIGS. 1 and 2 , the solid-liquid separation screen device 130 may include a filtration unit 131 in which a plurality of filtration holes 131a are formed. In addition, the solid-liquid separation screen device 130 may include a housing 132 connected to the filtration unit 131 . The plurality of filtration holes 131a may be formed to have a size to separate (remove) at least some of the foreign substances introduced together with the introduced rainwater. For example, the size of the filtration hole 131a is determined by the level of inflow rainwater (inflow rainwater, the amount of rainwater to be treated through the system of the present application, and the type and size of foreign substances included in the inflowing rainwater), as described above. It may be set in consideration of the size of the particles to be separated by the sedimentation separation unit 120 . Illustratively, the hole size of the filtering hole 131a may be about 5 mm, but is not limited thereto.

Also, referring to FIG. 4 , the plurality of filtering holes 131a formed in the filtering unit 131 may be formed along the circumference of the filtering unit 131 . As a more specific example, the filtration unit 131 may include a peripheral member in which a plurality of filtration holes 131a are formed. In addition, the filtration unit 131 may include a cover (131b) for covering one side (12 o'clock side in reference to FIG. 4) of the circumferential member. This cover (131b) may be provided to be detachable with respect to the circumferential member in order to secure the ease of maintenance. In addition, the filtration unit 131 may include a portion that is detachably coupled to the other side of the circumferential member (the 6 o'clock side in FIG. 4 ) through screw coupling with the housing 132 . As such, since the filtration unit 131 is detachably provided with respect to the housing 132, the cleaning operation of the filtration hole 131a for maintenance can be made more easily.

In addition, referring to FIGS. 1 and 2 , the inner surface of the side wall of the body 110 (corresponding to the outlet hole 113 ) so that the housing 132 of the solid-liquid separation screen device 130 communicates with the outlet hole 113 . It may be installed on the inner surface of the side wall), and the filtration unit 131 may be horizontally disposed so that the circumferential member is in a lying state with respect to the housing 132 (the central axis of the circumferential member faces the horizontal direction). The housing 132 may be connected to the filtration unit 131 so that rainwater separated into solid-liquid by the filtration unit 131 flows into the housing 132 . Referring to FIG. 2 as a specific example, the lower ends of the peripheral members of the filtration unit 131 may be mounted on the side surfaces of the housing 132 so that the insides of each other pass through. As such, as the filtration unit 131 is placed in a lying state, natural washing in the form of rainwater flowing in through the inlet hole 112 hitting the upper side of the circumferential surface (circumferential member) of the filtration unit 131 can be induced. have. In addition, the filtration unit 131 may be provided in a structure having a degree of freedom of rotation with respect to the housing 132 about the central axis of the lying state as described above. By giving such a degree of freedom of rotation, when the filtration unit 131 is rotated when hitting by the inflowing rainwater as described above, the blow to the circumferential surface can be made over a wider range (region or area).

Accordingly, foreign substances larger than the size of the plurality of filtration holes 131a of the solid-liquid separation screen device 130 can be separated (filtered), and referring to FIG. 2 , the solid-liquid separation screen device 130 is a solid-liquid separation It may be provided to discharge rainwater (result) through the rainwater outlet pipe 113a installed in the outlet hole 113 .

In addition, for example, referring to FIGS. 2 to 4 , the filtration unit 131 may be provided in a cylinder (cylindrical) shape of a mesh shape in which a plurality of filtration holes 131a are formed along the circumference. In addition, referring to FIGS. 2 and 3 , a plurality of filtration units 131 may be provided, and the number and size of each of these filtration units 131 are solid-liquid separated by the screen tank 100 and the outlet hole Set in consideration of the flow rate required by the result flowing out through 113 , the size (standard) of each filtration unit 131 , the size of the plurality of filtration holes 131a of each filtration unit 131 , etc. can be

In addition, referring to FIG. 3 , a plurality of filtration units 131 may be arranged at intervals in the horizontal direction, and may be arranged in multiple stages (multi-layers) in the vertical direction. In this case, the filtration units 131 adjacent in the upward direction may be alternately disposed so that a direct blow by rainwater flowing into the hollow part 111 may be more induced. More specifically, referring to FIG. 3 , a zigzag arrangement may be made such that the filtration units 131 of the lower layer are located in the interval between the filtration units 131 of the uppermost layer.

Also, for example, referring to FIG. 4 , the filtration unit 131 is a detachable connection coupling (eg, screw coupling) form with respect to the housing 132 (underwater screen box) of the solid-liquid separation screen device 130 . can be connected to Illustratively, the filtration unit 131 includes a screw portion (male thread) such as a bolt at the lower portion, and the housing 132 has a female screw hole corresponding to this, so that the screw portion of the filtration unit 131 can be coupled thereto. can do. Accordingly, the filtration unit 131 is easily separated from the housing 132 during cleaning or replacement, and is connected to the housing 132 by screwing the cleaned filtration unit 131 or a new filtration unit 131 in the form of a screw connection. It can be (mounted). This connection coupling part is separated into solid and liquid through the filtration hole 131a, and rainwater entering the filtration unit 131 moves to the housing 132 so that it can flow out through the outlet hole 113 communicating with the housing 132. , its interior may be provided to communicate with the interior of the housing 132 .

In addition, referring to FIGS. 1 to 3 , in the filtration unit 131 , the height of the plurality of filtration holes 131a may be lower than the height of the outlet hole 113 . For this reason, the filtration unit 131 can always be located in the water during storm water outflow to the outlet hole 113 . According to the arrangement height setting of the filtration unit 131, foreign substances adhering to the filtration unit 131 are not easily separated as they dry and solidify, and the filtration efficiency is sharply lowered due to clogging (blockage) of the filtration holes. The occurrence of the difficulty of shortening the maintenance cycle can be naturally reduced or prevented. That is, the filtration unit 131 can be placed in the water as much as possible through the arrangement position (height) setting, the removal of contaminants (foreign substances) attached thereto can be much easier compared to the prior art.

In addition, in consideration of the location of the inlet hole 113 in which the rainwater inlet pipe 112a is disposed, the arrangement position of the filtration unit 130 is relatively vortexed in water by rainwater introduced through the rainwater inlet pipe 112a. may be disposed at a position where there is a high possibility of forming the . Through the arrangement of the filtration unit 130 to the position where the vortex can be formed, the removal action of foreign substances attached by the underwater vortex is also made in the area of the filtration hole 131a of the filtration unit 130 that is not directly hit by the inflowing rainwater. can Illustratively, the rainwater inlet pipe 112a has a rainwater hole 113 and a rainwater inlet pipe 112a to discharge rainwater at an angle with a relatively high possibility of forming a vortex, and the rainwater inlet pipe 112a and A filtration unit 130 may be disposed with respect to the interlocking vortex-forming region.

In addition, referring to FIGS. 2 and 3 , the solid-liquid separation screen device 130 may include an inflow water guide plate 133 . The inflow water guide plate 133 may be installed at an upper position of the filtration unit 131 in the housing 132 to induce a vortex by rainwater introduced through the storm water inlet pipe 112a. For example, the inflow water guide plate 133 may be provided to extend obliquely (slope) upward from an upper position of the housing 132 . In this case, the upwardly extending inclined direction of the inflow water guide plate 133 may be a direction toward the inflow hole 112 in which the rainwater inlet pipe 112a is installed. In addition, the extended length of the inflow water guide plate 133, the inlet hole 112 (or the storm water inlet pipe 112a) and the inflow water guide plate 133 so that a vortex (or swirling vortex) formed by the inflowing rainwater can be formed more effectively. ) is preferably set appropriately.

By the inflow water guide plate 133, rainwater flowing in through the storm water inlet pipe 112a is not simply introduced, but a vortex (orbital vortex) in which the flow rate becomes faster or the direction of the flow is changed as it flows in is induced at least partially. can be, the advantage in terms of maintenance that can be more effectively removed for foreign substances (contaminants) adhering to the filtration unit 131 can be secured.

Also, referring to FIG. 4, the filtration unit 131 may include a circumferential member in which a plurality of filtering holes 131a are formed and a cover 131b removably covering one side (the 12 o'clock side in FIG. 4) of the circumferential member. can Accordingly, by separating the filtration unit 131 from the housing 132 when cleaning the filtration unit 131 , it is possible to easily perform maintenance such as washing the peripheral member formed in the filtration hole 131a.

Also, for example, referring to FIG. 2 , the solid-liquid separation screen device 130 may form an emergency overflow hole in the upper side of the housing 132 . In the emergency overflow hole, as the amount of rainwater flowing into the screen tank 100 rapidly increases due to short-time large-scale precipitation, etc., overflow may occur only through the filtering hole 131a of the filtration unit 131. If expected, or when the closure of the filtration hole 131a is excessive, it may be provided so that rainwater can enter the housing 132 without passing through the filtration hole 131a. The formation height of the emergency overflow hole is preferably set higher than the formation height of the outlet hole 113, and the height of the outlet hole 113 or the height of the filtration unit 131 is higher than the height of the outlet hole 113 by the height difference set in consideration of the continuity of precipitation in the area. It can be set higher.

This screen tank 100 uses the potential energy of rainwater flowing into the natural flow, so that various floating substances or sediments mixed in the rainwater (influent water) flowing into the screen tank 100 without a separate power source are used. It can be understood as a configuration (device) provided to reduce or remove foreign substances by filtering and sedimentation separation.
